What Is a Mill Rate?

In Connecticut, property tax rates are expressed in mills, or thousandths of a dollar.

For the fiscal year 2025-2026 the current property tax rate is 28.67 mills or .02867 when expressed in decimal form as a multiplier. This rate results in the payment of $28.67 for each $1,000 of a property's taxable assessed value.

Example:

$1,000 x .02867 = $28.67

This is called the mill rate because the number is expressed in mills. One mill is equal to 1/10th of a cent or $.001.
